What do psychedelics do to our brains? AI can help us learn

Big picture: Psychedelic drugs have long been touted as possible treatments for mental disorders such as depression and post-traumatic stress disorder. But very little is known about what these substances actually do to our brains. Understanding how they work can help unlock their potential.

New technique: Some scientists use AI to figure it out. A team at McGill University in Montreal used natural language processing to examine written “journey reports” from users who took a range of drugs. The team then combined this data with records of which neurotransmitter receptors in the brain each drug interacted with. Together, these steps allow the team to determine which receptors are associated with a particular drug experience.

What’s next: The work may shed light on how hallucinogens induce certain mental states, whether it be euphoria, anxiety, or a sense of oneness with the world. It could also help in the development of new drugs for mental disorders, which some firms are already trying to do. Read full story.
